  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiment described below is an embodiment when the present invention is applied to an information providing system.

[1. Overview of information provision system and functions]
First, the configuration and outline function of the information providing system S according to an embodiment of the present invention will be described with reference to FIG.

  FIG. 1 is a diagram illustrating an example of a schematic configuration of an information providing system S according to the present embodiment.

  As shown in FIG. 1, the information providing system S includes a user terminal 1 (an example of a terminal device), an information providing server 2 (an example of a server device), and a plurality of Web sites 3k (k = A, B... Any one of N). In the example of FIG. 1, one user terminal 1 is shown for convenience of explanation, but there are many user terminals 1 for each user.

  The user terminal 1 and the information providing server 2 or the Web site 3k can exchange data with each other using, for example, TCP / IP as a communication protocol via the network NW. The network NW is constructed by, for example, the Internet, a dedicated communication line (for example, a CATV (Community Antenna Television) line), a mobile communication network (including a base station), a gateway, and the like.

  Each Web site 3k includes a Web server to which a unique domain name is assigned. Each Web site 3k is assigned a unique site ID. This site ID may be, for example, the URL or domain name of each Web site 3k. A plurality of Web pages are registered in each Web site 3k. Each web page is assigned a unique page ID. This page ID (Web page specifying information) may be the URL of each Web page, for example. The Web page is composed of a structured document file such as an HTML (Hyper Text Markup Language) or XML (Extensible Markup Language) file, image data, and the like.

  The user terminal 1 is, for example, a personal computer, a PDA (Personal Digital Assistant), a mobile phone, or the like, and has a Web browser function. The user terminal 1 uses a Web browser to access the Web site 3k, obtain a Web page, and display the Web page in a window screen that appears on the display. Thereby, the user can browse the Web page provided from the Web site 3k. Note that the window screen is an active display area of the Web browser. In the case of full screen display, the active display area is the full screen.

  In addition, when a part of the display area of the Web page cannot fit in the window screen appearing on the display of the user terminal 1, the user terminal 1 displays the display area of the Web page in the window screen in response to the scroll operation by the user. Scroll (move within the active display area of the Web browser) in the horizontal direction, vertical direction, diagonal direction, or the like (area where text or images are displayed). Here, as an example of the scroll operation by the user, the user rotates the wheel (the button between the left and right buttons) of the mouse (the operation unit of the user terminal 1), and the user displays the scroll bar displayed near the window screen. Is moved by the drag function of the mouse, the user presses the upper, lower, left, or right key of the keyboard (the operation unit of the user terminal 1), and the window screen is displayed by the user using a pointing device such as a mouse. For example, dragging to move an active display area in an arbitrary direction, and flicking (for example, lightly touching with a finger) the user on a touch panel type window screen.

  Then, the Web browser of the user terminal 1 acquires scroll operation information related to the scroll when the Web page is scrolled according to the scroll operation (an example of scroll operation information related to the Web page). Subsequently, the Web browser of the user terminal 1 creates an operation information file including the acquired scroll operation information, the page ID of the Web page, and the site ID of the Web site 3k that provided the Web page. Then, the Web browser of the user terminal 1 transmits the created operation information file and the user ID stored in the user terminal 1 to the information providing server 2 via the network NW.

  The Web browser incorporates a program (for example, plug-in software for extending the browser function) for acquiring scroll operation information, creating an operation information file, and transmitting the operation information file to the information providing server 2. Yes. In this program, information such as an IP address necessary for accessing the information providing server 2 and information such as the transmission timing of the operation information file are defined. The operation information file transmission timing is, for example, at the end of the scroll operation for executing the scroll as the acquisition target of the scroll operation information. When the start and end of scrolling are repeated while a certain Web page is displayed, the operation information file and the user ID are transmitted to the information providing server 2 each time.

  In addition, the scroll operation information stored in the operation information file includes, for example, a scroll operation speed, a scroll operation time, and the like, and these are used to determine the user's interest in the web page.

  Here, the scroll operation speed is a speed at which the web page scrolls. For example, a value obtained by dividing the shift amount of the Web page in the window screen by the scroll operation time related to the shift (movement) is detected (calculated) as the scroll operation speed. The above-mentioned “change amount” is, for example, an arbitrary pixel (or pixel group) displayed on the window screen displayed on the window screen from the first coordinate (x1, y1) to the second coordinate (x2, y2). This corresponds to the distance between the first coordinate and the second coordinate when moved to. The “scroll operation time” is, for example, the time during which the web page is scrolling (that is, the time from the start of the scroll operation to the end of the scroll operation) (calculated by the time measuring program).

  Note that the web browser of the user terminal 1 calculates the time from the start of displaying the web page to the end of displaying the web page (hereinafter referred to as “page stay time”), and calculates the page ID of the web page and the web page. An operation information file including the site ID of the provided website 3k and information indicating the page stay time and a user ID are transmitted to the information providing server 2 via the network NW. Here, the display of the Web page is terminated by a user operation such as designation of a hyperlink (clicking with a mouse, etc.), pressing of a return button of the Web browser or a close button of the Web browser.

  Further, the user terminal 1 displays a Web page (an example of Web site list information, hereinafter referred to as “site list page”) indicating a list of Web sites transmitted from the information providing server 2 or a list of Web pages. Web page (an example of Web page list information, referred to as “page list page”) is received and displayed on the display. The site list page is a web page for displaying a list of a plurality of websites (in this example, any one of 3A to 3N). The page list page is a web page for displaying a list of a plurality of web pages.

[2. Configuration and function of information providing server 2]
Next, the configuration and function of the information providing server 2 will be described with reference to FIG.

  FIG. 2 is a block diagram illustrating an example of a schematic configuration of the information providing server 2 according to the present embodiment.

  As shown in FIG. 2, the information providing server 2 includes a communication unit 21, a storage unit 22, an input / output interface unit 23, and a system control unit 24. The system control unit 24 and the input / output interface unit 23 are connected via a system bus 25.

  The communication unit 21 is connected to the network NW and controls the communication state with the user terminal 1.

  The storage unit 22 is configured by a hard disk drive, for example, and stores various programs such as an operating system and an information providing program. Note that the information providing program of the present invention may be acquired from, for example, another server device or the like via a network NW, or may be recorded on a recording medium and read via a drive device. good.

  The storage unit 22 (an example of a storage unit) stores data (for example, an HTML file, image data, etc.) for configuring a Web page provided to the user terminal 1.

  The storage unit 22 includes a user information database (DB) 221, an authentication information database (DB) 222, a site information database (DB) 223, an operation information database (DB) 224, and a retargeting information database (DB) 225. Has been built.

  FIG. 3 is a diagram illustrating a configuration example of information registered in each database.

  In the user information database 221 shown in FIG. 3A, user information such as user ID, name, sex, address, telephone number, and mail address of a registered user is associated and registered for each user. Yes.

  In the authentication information database 222 shown in FIG. 3B, a user ID, a login ID, and a password are registered in association with each user. The login ID and password are authentication information used for login processing (user authentication processing).

  In the site information database 223 shown in FIG. 3C, a site ID and a page ID are registered in association with each Web site. Usually, since a plurality of Web pages are registered in one Web site, a plurality of page IDs are registered in the site information database 223 in association with one site ID.

  Although not shown, in the site information database 223, for each Web page, information related to the Web page (for example, a summary of a text or an image displayed on the Web page) is registered in association with the page ID. . In the site information database 223, for each website 3k, information about the website (for example, the name and image of the website 3k) is registered in association with the site ID.

  In the operation information database 224 shown in FIG. 3D, the user ID, page ID, scroll operation speed (for multiple times), scroll operation speed_average value, scroll operation speed_maximum frequency, scroll operation speed_maximum value, scroll Operation speed_minimum value, scroll operation time, and page stay time are registered in association with each user. That is, the operation information database 224 stores the scroll operation information and the page ID corresponding to each of the plurality of Web pages provided from the plurality of Web sites 3k so as to be discriminated. In addition, since the scroll operation speed is normally detected a plurality of times for one Web page display, the scroll operation speed for a plurality of times is registered.

  Here, the scroll operation speed_average value is an average value of the scroll operation speeds detected a plurality of times. The scroll operation speed_maximum frequency is the scroll operation speed having the highest appearance frequency among the scroll operation speeds detected a plurality of times. The scroll operation speed_maximum value is the maximum value among the scroll operation speeds detected a plurality of times. The scroll operation speed_minimum value is the minimum value among the scroll operation speeds detected a plurality of times. The scroll operation speed_average value, the scroll operation speed_maximum frequency, the scroll operation speed_maximum value, and the scroll operation speed_minimum value may be calculated by the user terminal 1 and included in the scroll operation information. Alternatively, it may be configured to be calculated by the system control unit 24 of the information providing server 2.

  In the retargeting information database 225 shown in FIG. 3E, the user ID, site ID, page ID, site display order, page display order (by site), and page display order (common to sites) correspond to each user. Attached and registered.

  Here, the site display order is a display order among the plurality of Web sites 3k in the site list page. The page display order (by site) is a display order among a plurality of Web pages registered in the same Web site 3k in the site list page or page list page. The page display order (common to sites) is the display order among all Web pages registered in each Web site 3k in the page list page.

  FIG. 4 is a diagram illustrating a specific example of information registered in the retargeting information database 225. In the example shown in FIG. 4, the site ID is the URL of the Web site 3k, and the page ID is the URL of the Web page registered in the Web site 3k.

  In the example shown in FIG. 4, the Web page corresponding to No. 4 from the Web page corresponding to No. 1 is a Web page registered in the Web site 3A. Further, since the display order of the Web site 3A is first (highest), the information related to the Web site 3A is displayed at the position most noticeable by the user on the site list page. Also, among the Web pages registered in the Web site 3A, the display order of the Web page corresponding to No. 1 is second. In addition, the display order of the Web page corresponding to No. 1 is third in all the Web pages.

  The input / output interface unit 23 performs interface processing between the communication unit 21, the storage unit 22, and the system control unit 24.

  The system control unit 24 includes a CPU (Central Processing Unit) 24a, a ROM (Read Only Memory) 24b, a RAM (Random Access Memory) 24c, and the like. In the system control unit 24, the CPU 24a reads out and executes various programs stored in the ROM 24b and the storage unit 22, thereby performing web page provision processing and the like.

  Further, the system control unit 24 includes an information acquisition unit, a display order determination unit, a Web page list information transmission unit, a Web site list information transmission unit, a Web page information extraction unit, a terminal information acquisition unit, an extraction range determination unit, And functions as a display control means.

  Specifically, the system control unit 24 acquires the operation information file and the user ID transmitted from the user terminal 1, and the scroll operation information, the site ID, the page ID, the user ID, and the user ID included in the operation information file. Are registered (stored) in the operation information database 224 in association with each other. At this time, if the operation information file does not include the scroll operation speed_average value, the scroll operation speed_maximum frequency, the scroll operation speed_maximum value, and the scroll operation speed_minimum value, the system control unit 24 The scroll operation speed is calculated and registered in the operation information database 224.

  Further, the system control unit 24 extracts the scroll operation information and the page ID associated with the user ID of a certain user from the operation information database 224, and based on the extracted scroll operation information, the extracted page ID The degree of interest of the user with respect to the Web page specified by is determined (calculated) for each Web page. Note that the degree of interest of the user is expressed by, for example, a score (numerical value). The higher the score, the higher the degree of interest (in other words, the more interested), and the lower the score, the lower the degree of interest (in other words, the more interested). May be determined).

  For example, the system control unit 24 calculates the interest level to be greater as the “scroll operation speed” is slower. In this case, for example, it is calculated by a calculation formula of Sc (degree of interest) = α (arbitrary coefficient) / v (scroll operation speed). In this calculation formula, α> 0 and v> 0.

  Further, for example, the system control unit 24 may be configured to calculate such that the degree of interest increases as the “scroll operation speed / page stay time” decreases. In this case, for example, Sc (degree of interest) = α (arbitrary coefficient) / (v (scroll operation speed) / Tt (page stay time)) is calculated. In this calculation formula, (v / Tt)> 0. Further, in this calculation formula, a scroll operation time may be used instead of the page stay time Tt.

  In addition, it can be said that the higher the change frequency of the scroll operation speed (the more the change in acceleration), the higher the degree of interest because the user repeats scrolling faster and slower. Therefore, the system control unit 24 may be configured to calculate such that the degree of interest increases as the change frequency of the scroll operation speed increases. In this case, for example, it is calculated by a calculation formula of Sc (degree of interest) = α (arbitrary coefficient) * m (change frequency of scroll operation speed). Here, the change frequency of the scroll operation speed is, for example, a difference between two scroll operation speeds adjacent in time series among a predetermined number (for example, 10) of the scroll operation speeds detected a plurality of times. Is obtained by calculating a number whose absolute value is equal to or greater than a threshold value.

  As described above, in calculating the degree of interest using the scroll operation speed, any one of the scroll operation speed_average value, the scroll operation speed_maximum frequency, the scroll operation speed_maximum value, and the scroll operation speed_minimum value is selected. One is used.

  In the above example, the degree of interest is calculated based on the scroll operation speed. However, as another example, the integrated value (total of each scroll operation time from the start of Web page display to the end of Web page display). ) May be configured to calculate the degree of interest. The integrated value of the scroll operation time is an integrated time during scrolling excluding the time during which the scroll is stopped when the scroll of the Web page is temporarily stopped and the scroll is resumed. For example, the system control unit 24 calculates the interest level to be greater as the scroll operation time (integrated value) is longer. In this case, for example, Sc (degree of interest) = α (arbitrary coefficient) * t (scroll operation time (integrated value)) is calculated.

  Then, the system control unit 24 sets the display order of the Web pages (for example, the display order for each site and the display order common to the sites) based on the calculated user interest level for each Web page (for example, in descending order of interest). decide. For example, it is determined that the display order is higher in the Web page having a higher calculated interest level. The page display order (for each site and for each site) determined in this way is registered in the retargeting information database 225 together with the page ID of each Web page.

  The system control unit 24 calculates the display order of the Web pages specified by each extracted page ID based on each extracted scroll operation information without calculating the user's interest level for each Web page (for each site). The display order and the display order common to the sites may be determined. In this case, for example, the scroll operation speeds of the respective Web pages are compared, and the Web page with the slower scroll operation speed is determined so that the display order is higher.

  Further, the system control unit 24 extracts scroll operation information corresponding to each of a plurality of Web pages from the operation information database 224 for each Web site 3k, and based on each scroll operation information extracted for each Web site 3k. The display order of each Web site 3k may be determined. For example, the system control unit 24 calculates the average value of the interest level for each Web page registered in the Web site 3k for each Web site 3k, and based on the average value (for example, the average value of the interest level is large). In order) determine the display order of the website 3k. For example, the Web site 3k having a larger average value of the calculated interest level is determined to have a higher display order. In the example shown in FIG. 4, the average value of the interest level of the Web site 3A is a value obtained by dividing the value obtained by integrating the interest levels of the Web pages corresponding to No. 1 to No. 4 by 4. The site display order of each Web site 3k determined in this way is registered in the retargeting information database 225 together with the site ID of each Web site 3k.

  Note that the system control unit 24 may be configured to determine the display order of the Web site 3k based on each scroll operation information without calculating the user's interest in each Web page. In this case, for example, the average value of the scroll operation speed of the Web page is calculated for each Web site 3k, and the display order is determined to be higher in the Web site 3k having a lower average value of the scroll operation speed.

  Then, the system control unit 24 displays a list of web pages (listing results) configured in the determined display order when the user of the user terminal 1 logs in (or when accessing the specific site from the user terminal 1). The page list page shown is transmitted to the user terminal 1. Here, the system control unit 24 determines a predetermined range (for example, the display order from 1st to 5th, or the display order is only 1 from the information indicating the list of Web pages configured in the determined display order. ) May be extracted, and a page list page indicating a list of Web pages in the extracted range may be transmitted to the user terminal 1.

  The system control unit 24 transmits to the user terminal 1 a site list page indicating a list of Web sites 3k when the user of the user terminal 1 logs in (or when accessing the specific site from the user terminal 1). Then, the system control unit 24 lists web pages corresponding to the website 3k designated by the user from the list of websites 3k displayed on the display of the user terminal 1 (provided by the website 3k). May be displayed on the user terminal 1 in the determined display order. The list of websites 3k on the site list page may be, for example, a list configured in the order of website registration in the site information database 223, but the website configured in the determined display order of the website 3k. If it is configured to be a 3k list, it is more convenient for the user.

[3. Operation of information provision system]
Next, the operation of the information providing system S according to the present embodiment will be described.

(3.1. Creation and transmission of operation information file)
First, the creation and transmission processing of the operation information file by the user terminal 1 will be described with reference to FIG.

  FIG. 5 is a flowchart showing an operation information file creation and transmission process in the user terminal 1. The processing shown in FIG. 5 is transmitted from the Web site 3A as a response to an access request (for example, an HTTP (Hyper Text Transfer Protocol) request) from the user terminal 1 to the Web site 3A after the Web browser is activated on the user terminal 1, for example. This is started when the web page is received and displayed by the user terminal 1. Note that the page ID of the Web page and the site ID of the Web site 3A are added to the Web page.

  When the process shown in FIG. 5 is started, the Web browser of the user terminal 1 determines whether or not the scroll operation by the user has been started based on an operation signal related to the scroll operation from the operation unit (step S1). If it is determined that the scroll operation has been started (step S1: YES), the above-described timer for measuring the scroll operation time is started, the process proceeds to step S2, and it is determined that the scroll operation has not been started. In the case (step S1: NO), the process proceeds to step S7.

  In step S2, the web browser of the user terminal 1 executes scroll processing for scrolling the web page displayed in the window screen in response to the scroll operation.

  Next, the Web browser of the user terminal 1 determines whether or not the scroll operation has been completed based on an operation signal related to the scroll operation from the operation unit (step S3). For example, when there is no scrolling operation for a predetermined time (for example, 0.5 seconds) (the operation signal related to the scrolling operation is not given for a predetermined time from the operation unit), the web browser of the user terminal 1 determines that the scrolling operation has ended. (Step S3: YES), the counting of the timer for measuring the scroll operation time described above is stopped, and the process proceeds to Step S4. On the other hand, if the Web browser of the user terminal 1 determines that the scroll operation has not ended (step S3: NO), the process returns to step S2 and continues the scroll process.

  In step S4, the Web browser of the user terminal 1 executes a scroll operation information acquisition process related to the scroll when the Web page is scrolled according to the scroll operation. Specifically, the Web browser of the user terminal 1 detects a scroll operation speed by calculating the amount of change that the Web page has changed in the window screen and dividing the amount of change by the measured scroll operation time ( calculate.

  Next, the Web browser of the user terminal 1 acquires the page ID of the scrolled Web page and the site ID of the Web site 3A that provided the Web page (Step S5).

  Next, the Web browser of the user terminal 1 creates an operation information file including the acquired scroll operation information, site ID, and page ID (step S6), and temporarily stores it in the RAM.

  In step S <b> 7, the Web browser of the user terminal 1 determines whether or not the operation information file transmission timing condition is satisfied. For example, when “at the end of the scroll operation for executing the scroll for which the scroll operation information is acquired” is defined as the transmission timing, the transmission timing condition is satisfied (step S7: YES) ), The process proceeds to step S8, and if the condition is not satisfied (step S7: NO), the process proceeds to step S9.

  In step S8, the Web browser of the user terminal 1 transmits the operation information file created in step S6 and the user ID stored in advance to the information providing server 2 via the network NW.

  The transmission timing may be defined as “at the start of the scroll operation for executing the next scroll after the end of the scroll as the acquisition target of the scroll operation information”. In this case, the operation information file created in step S6 is transmitted to the information providing server 2 when the scroll operation for executing the next scroll is started after the end of the scroll as the acquisition target of the scroll operation information. The

  Alternatively, the transmission timing may be defined as “at the time of designation (or selection) by the user other than the scroll operation after the end of the scroll as the acquisition target of the scroll operation information”. In this case, the operation information file created in step S6 is transmitted to the information providing server 2 when the user designates (or selects) an operation other than the scroll operation after the end of the scroll as the acquisition target of the scroll operation information. Is done. The designation (or selection) by the user other than the scroll operation is, for example, designation of various buttons such as a purchase button, a reservation button, or a settlement button (clicking with a mouse), or jumping to another Web page. For example, link designation.

  Alternatively, the transmission timing may be defined as “when a predetermined time has elapsed since the previous transmission of the operation information file”. In this case, the operation information file created in step S6 is transmitted to the information providing server 2 every predetermined time (for example, 1 minute).

  Alternatively, the transmission timing may be defined as “when a predetermined amount of data accumulation is detected”. In this case, every time a predetermined amount of operation information file data is accumulated, the operation information file created in step S6 is transmitted to the information providing server 2.

  In step S <b> 9, the web browser of the user terminal 1 determines whether there is a web page display end instruction. For example, when the user designates a web page close button (or back button) or when a hyperlink for jumping to another web page is designated, the web browser of the user terminal 1 It is determined that there is a display end instruction (step S9: YES), and the process proceeds to step S11. On the other hand, if the Web browser of the user terminal 1 determines that there is no instruction to end the display of the Web page (step S9: NO), the process proceeds to step S10, and other processing (for example, processing according to an input operation by the user). And return to step S1.

  In step S11, the Web browser of the user terminal 1 calculates a page stay time, creates an operation information file including information indicating the page stay time, a page ID, and a site ID. The stored user ID is transmitted to the information providing server 2 via the network NW, and the process ends.

  The “scroll operation time” used in step S4 is the time from the start of the scroll operation to the end of the scroll operation. If the scroll operation speed is calculated using this time, for example, the user can quickly scroll. If the user performs a scrolling operation such as pausing and browsing the web page and scrolling again, the user may not be able to determine the exact degree of interest.

  Therefore, in consideration of such cases, if the “scroll operation time” is the time from the start of the scroll operation to the start of the next scroll operation, the user quickly scrolls and then pauses the Web page. Even when a scroll operation such as browsing carefully and scrolling again is performed, it is possible to determine an appropriate degree of interest of the user. Here, the time from the start of the scroll operation to the start of the next scroll operation is specifically, the scroll pause time from the start of the scroll operation for which the scroll operation information is acquired. And the time until the start of the scroll operation for executing the next scroll. In this case, when the Web browser of the user terminal 1 determines that the scroll operation has ended in step S3, the next scroll operation is started without stopping the counting of the timer for measuring the scroll operation time described above. Stop when In step S4, the Web browser of the user terminal 1 uses the measured scroll operation time (the time from the start of the scroll operation to the start of the next scroll operation) as the amount of change that the Web page has changed in the window screen. The scroll operation speed is calculated by dividing by. In this case, the Web browser of the user terminal 1 calculates the scroll operation calculated in step S8 when the scroll operation for executing the next scroll is started after the end of the scroll as the acquisition target of the scroll operation information. An operation information file including speed is transmitted to the information providing server 2.

  FIG. 6 is a conceptual diagram showing an example of the relationship between the amount of web page transition and scroll operation time. In the period P1 shown in FIG. 6, “t1” is the scrolling time (that is, the time from the start of the scroll operation to the end of the scroll operation), “t2” is the scroll pause time, and “t3” "(= T1 + t2) is the time from the start of the scroll operation to the start of the next scroll operation. Further, in the period P1 shown in FIG. 6, “d1” is a shift amount due to scrolling.

  When “t1” is used as the scroll operation time, the scroll operation speed v1 = d1 / t1. On the other hand, when “t3” is used as the scroll operation time, the scroll operation speed v3 = d1 / t3. As described above, when the scroll operation speed is calculated using “t1” as the scroll operation time in the period P1, the speed is relatively high, and therefore it is determined that the degree of interest of the user is low. On the other hand, when the scroll operation speed is calculated using “t3” including the scroll pause time as the scroll operation time, the speed is relatively slow, and therefore it is determined that the degree of interest of the user is high. Can do.

  If the scroll operation time is “time from the start of the scroll operation to the start of the next scroll operation”, the next scroll operation is not started in the period P4 shown in FIG. Therefore, in this period P4, the scroll operation time and the scroll operation speed are not calculated. If the scroll operation speed_average value is calculated, only three scroll operation speeds in the periods P1 to P3 are used, and the period P4 is not considered.

  In the process shown in FIG. 5, the operation information file is transmitted to the information providing server 2 every time the web page is displayed and scrolled. However, as another example, the operation information file is created. The stored operation information file and the user ID are stored in the information providing server when the user terminal 1 makes a login request or the like to the information providing server 2. 2 may be configured to be transmitted.

  Further, the operation information file may be configured to store information about the website 3A and information about the web page provided from the website 3A.

  In the above operation example, the Web site 3A is taken as an example, but the same applies to other Web sites 3k.

(3.2. Registration of scroll operation information, etc.)
Next, registration processing of scroll operation information and the like by the information providing server 2 will be described with reference to FIG.

  FIG. 7 is a flowchart showing registration processing of scroll operation information and the like in the system control unit 24 of the information providing server 2. The process illustrated in FIG. 7 is started when the operation information file and the user ID transmitted from the user terminal 1 are received.

  When the process shown in FIG. 7 is started, the system control unit 24 of the information providing server 2 acquires scroll operation information, a site ID, and a page ID from the received operation information file (step S21).

  Next, the system control unit 24 registers the acquired scroll operation information, site ID, and page ID in the operation information database 224 in association with the received user ID (step S22), and ends the process.

  When information related to a website is stored in the operation information file, information related to the website and a site ID are associated and registered in the site information database 223. Further, when information related to a Web page is stored, information related to the Web page and a page ID are associated with each other and registered in the site information database 223.

  In the above example, the user terminal 1 is configured to calculate the scroll operation speed. However, the information providing server 2 may be configured to calculate the scroll operation speed. In this case, the “transition amount of the Web page” calculated by the user terminal 1 and the “scroll operation time” (“time from the start of the scroll operation to the end of the scroll operation” or “the start of the scroll operation until the next scroll operation” "Time until start") is included in the operation information file and transmitted to the information providing server 2. Then, the scroll operation speed is calculated by the system control unit 24 based on the “Web page transition amount” and the “scroll operation time” and registered in the operation information database 224.

  The process shown in FIG. 7 is also performed when an operation information file including a page stay time, a page ID, and a site ID and a user ID are received from the user terminal 1.

(3.3. Provision of Web page list)
Next, Web page list provision processing by the information providing server 2 will be described with reference to FIG.

  FIG. 8 is a flowchart showing a Web page list providing process in the system control unit 24 of the information providing server 2. As a premise of this process, the user information of the user of the user terminal 1 is already registered in the user information database 221 by the member registration process, and the authentication information of the user is already registered in the authentication information database 222. It shall be.

  In the process shown in FIG. 8, the information providing server 2 performs a login process in response to a login request (including a login ID and a password) from the accessed user terminal 1, and specifies the user ID of the user terminal 1. And started. In the login process, it is determined whether or not a combination of a login ID and a password included in the login request is registered in the authentication information database 222. If the pair is registered, the user ID is specified.

  When the processing shown in FIG. 8 is started, the system control unit 24 of the information providing server 2 obtains the page ID associated with the identified user ID and the scroll operation information associated therewith from the operation information database 224. Extract (step S31).

  Next, based on the scroll operation information associated with each extracted page ID, the system control unit 24 determines the degree of interest of the user for the Web page specified by the page ID for each Web page as described above. Calculate (step S32).

  Next, the system control unit 24 determines the common display order of Web pages based on the calculated degrees of interest as described above (step S33). In this way, the page display order (common to sites) of each Web page is determined.

  Next, the system control unit 24 associates the determined page display order of each Web page (common to sites), the page ID of each Web page, and the specified user ID, and registers them in the retargeting information database 225 (Step S24). S34).

  Next, the system control unit 24 generates a page list page indicating a list of Web pages configured by the page display order (common to sites) of each Web page registered in the retargeting information database 225 (Step S35). Note that the system control unit 24 determines a predetermined range (for example, the display order is 1 from the information indicating the list of Web pages configured by the page display order (common to sites) of each Web page registered in the retargeting information database 225. It is also possible to extract the information of the Web pages from the first to the fifth rank (or the display order is only 1) and generate a page list page indicating a list of Web pages in the extracted range.

  Next, the system control unit 24 of the information providing server 2 transmits the generated page list page to the user terminal 1 that transmitted the login request (step S36). Note that the list of Web pages may be, for example, a list of URLs of Web pages, or a list of information about Web pages (for example, summary of texts and images displayed on Web pages). .

  The page list page transmitted in this way is displayed on the display of the user terminal 1.

  FIG. 9 is a diagram illustrating an example of display contents of the page list page. In the example shown in FIG. 9, a summary list of sentences displayed on each Web page is displayed on the page list page in the common display order determined by the system control unit 24 of the information providing server 2. Yes. In each summary displayed in this way, the URL of each Web page is set. Then, when a summary of a desired Web page is designated by the user of the user terminal 1 (for example, clicked with a mouse), the Web browser of the user terminal 1 accesses the Web site 3k that registers the Web page by a hyperlink. The Web page is acquired and displayed on the display.

(3.4. Providing a list of Web pages through providing a list of Web sites)
Next, Web page list provision processing through provision of a website list by the information providing server 2 will be described with reference to FIG.

  FIG. 10 is a flowchart showing Web page list provision processing through provision of a website list in the system control unit 24 of the information providing server 2.

  The process shown in FIG. 10 is started when the login process is performed and the user ID of the user terminal 1 is specified, similarly to the process shown in FIG.

  When the processing shown in FIG. 10 is started, the system control unit 24 operates the operation information on all (or a predetermined number) of page IDs and all (or a predetermined number) of scroll operation information associated with the specified user ID. While acquiring from the database 224, the site ID matched with each acquired page ID is acquired from the site information database 223 (step S41).

  Next, the system control unit 24 classifies the acquired plurality of scroll operation information for each Web site 3k based on the acquired site ID and page ID (step S42). That is, scroll operation information associated with the same site ID (via the page ID) is collected.

  Next, as described above, the system control unit 24 calculates the degree of interest of the user for each Web page for each Web site 3k based on the classified scroll operation information (step S43).

  Next, as described above, the system control unit 24 determines the display order of each Web page for each Web site 3k based on the calculated degree of interest of the user with respect to each Web page (step S44). . In this way, the page display order (by site) of each Web page is determined.

  Next, the system control unit 24 calculates the average value of the interest level of the user for each Web page for each Web site 3k, and determines the display order of the Web site 3k based on the average value (step S45). ). In this way, the site display order of each Web site 3k is determined.

  Next, the system control unit 24, the determined site display order of each Web site 3k, the determined page display order of each Web page (by site), the site ID of each Web site 3k, the page ID of each Web page, Then, the identified user ID is associated and registered in the retargeting information database 225 (step S46).

  Next, the system control unit 24 generates a site list page indicating a list of websites configured by the site display order of each website 3k registered in the retargeting information database 225 (step S47).

  Next, the system control unit 24 transmits the generated site list page to the user terminal 1 that has transmitted the login request (step S48).

  The list of websites may be, for example, a list of URLs of the website 3k, or a list of information related to the website 3k (for example, the name and image of the website 3k). Further, the site list page includes, for example, the page ID of the Web page provided from each Web site 3k, the page display order (by site), and information on the Web page.

  The site list page transmitted in this way is displayed on the display of the user terminal 1.

  FIG. 11 is a diagram illustrating an example of display contents of the site list page. In the example shown in FIG. 11A, a list of names of the Web sites 3k is displayed on the site list page in the display order determined by the system control unit 24 of the information providing server 2. When the user designates a desired website 3k from the list of websites displayed in this manner (for example, mouse over the name of the website 3k) using the operation unit, the web browser of the user terminal 1 As shown in FIG. 11B, a list of Web pages 100 corresponding to the specified Web site 3k is displayed in the display order for each site determined by the system control unit 24 of the information providing server 2.

  In the example shown in FIG. 11B, a summary list of sentences displayed on each Web page is displayed. Note that the page display order (by site) for displaying the web page list 100 and information on the web page are provided by the web browser of the user terminal 1 when the mouse is moved over the name of the web site 3k. You may comprise so that it may acquire from the server 2. FIG.

  Further, the name of each website 3k shown in FIG. 11A is configured such that the URL of each website 3k is set, and the user designates a desired website 3k using the operation unit (for example, the website 3k). When the name of the site 3k is clicked with a mouse), the Web browser of the user terminal 1 may be configured to access the Web site 3k via a hyperlink to obtain a representative Web page and display it on the display. good.

  As another example, the user designates a desired website 3k from the list of websites 3k displayed as shown in FIG. 11A using the operation unit (for example, the name of the website 3k is specified). When clicked with the mouse, the Web browser of the user terminal 1 may request the information providing server 2 for a page list page. In this case, the system control unit 24 of the information providing server 2 displays the page of each Web page (Web page provided from the specified Web site 3k) registered in the retargeting information database 225 in response to the request. A page list page indicating a list of Web pages configured by rank (by site) is generated, and the page list page is returned to the user terminal 1. Then, when the Web browser of the user terminal 1 receives the page list page, it displays it on the display.

  The calculation of the degree of interest, the determination of the site display order, the determination of the page display order, and the registration in the retargeting information database 225 are configured to be executed by specifying the user ID by the login process. However, as another example, the calculation of the degree of interest, the determination of the site display order, the determination of the page display order, and the registration in the retargeting information database 225 are not limited to the login process in particular. 12 hours) may be executed at intervals.

  As described above, according to the above-described embodiment, the information providing server 2 acquires the scroll operation information related to the scroll when the Web page displayed on the user terminal 1 is scrolled according to the scroll operation by the user. Since the display order of the Web pages is determined based on the scroll operation information, a page list page indicating a list of Web pages configured in the determined display order is transmitted to the user terminal 1 and displayed. The user does not feel complicated (because the user does not have to register favorite web pages as favorites), and also does not cause trouble on the server operator side. Because the URL does not need to be registered in advance, the user can display a list of web pages of interest There can be seen on the Web page order, it is possible to browse quickly the Web page of interest to the user.

  Further, the information providing server 2 extracts the information of the Web pages from the information indicating the list of Web pages configured in the display order of each Web page to the predetermined range, and the page indicating the list of Web pages in the extracted range If the list page is transmitted to the user terminal 1 and displayed, the legibility of the user terminal 1 by the user can be improved.

  Further, the information providing server 2 is configured to calculate the user's interest level for each Web page based on the scroll operation information, and to determine the display order of the Web pages based on the interest level. The display order in which the height of (interesting degree) is directly reflected can be determined.

  In particular, since the level of interest is determined depending on whether the scroll operation speed by the user is fast or slow, it is possible to determine the degree of interest with high accuracy without being particularly conscious of the user during the normal operation of the scroll operation.

  Further, the information providing server 2 transmits a site list page showing a list of the websites 3k to the user terminal 1 for display, and displays the website list 3k designated by the user from the displayed list of websites 3k. According to the configuration in which the list of corresponding web pages is displayed on the user terminal 1 in the determined display order, the user efficiently views the list of web pages displayed in descending order of interest for each website 3k. be able to. At this time, if the display order of the Web site 3k is also determined based on the scroll operation information (interesting level) at the time of browsing the Web page, the user can efficiently access the Web page from the high-interesting Web site 3k. You can see a list.

[4. Adjustment of interest level by screen size]
In the above embodiment, the information providing server 2 is configured to adjust the interest level by weighting according to the screen size of the Web browser of the user terminal 1 when calculating the interest level based on the scroll operation information. Also good.

  In this case, the Web browser of the user terminal 1 creates an operation information file including screen size information indicating the screen size in addition to the scroll operation information, the site ID, and the page ID, and stores the operation information file and the user ID. It transmits to the information providing server 2. Note that the screen size of the Web browser can be acquired by JavaScript (registered trademark).

  When the system control unit 24 of the information providing server 2 receives the operation information file from the user terminal 1, the system control unit 24 acquires scroll operation information, a site ID, a page ID, and screen size information from the operation information file. In association with the user ID, scroll operation information, site ID, page ID, and screen size information are registered in the operation information database 224.

  Then, the system control unit 24 of the information providing server 2 extracts the scroll operation information, the page ID, and the screen size information associated with the user ID from the operation information database 224, and based on the extracted scroll operation information. When calculating the degree of interest, the degree of interest is adjusted by weighting according to the screen size indicated in the extracted screen size information.

  For example, when the interest level is calculated by a formula of Sc (degree of interest) = α (arbitrary coefficient) / v (scrolling operation speed), α is a weight, and the screen size is a predetermined screen reference size ( For example, when the screen size is larger than 800 dots wide (600 dots wide) (for example, the area is large), the screen size is smaller than “α” (for example, α = 100) when the screen size is the same (for example, α = 100). 80) to adjust the degree of interest. This is because when the screen size is larger than the screen reference size, it takes time to grasp the contents of the Web page, and the scroll operation speed tends to be slow (that is, the user is not interested in much, but is interested in it). This is to reduce the degree of interest.

  On the other hand, when the screen size is smaller than the predefined screen reference size (for example, the area is small), it is larger than “α” (for example, α = 100) when the screen size is the same as the screen reference size (for example, α = 100) ( For example, the interest level is adjusted by α = 120). This is because when the screen size is smaller than the screen reference size, it takes a short time to grasp the contents of the Web page, and the scrolling operation speed tends to increase (that is, the user is interested in spite of interest). This is to increase the degree of interest.

  According to such a configuration, for example, even when one user uses a user terminal having a large screen size (for example, a PC) and a user terminal having a small screen size (for example, a PDA), Each degree of interest calculated using the scroll operation speed detected by the user terminal can be used in common.

  It should be noted that Web page information from a Web page list configured in the display order of each Web page to a predetermined range is extracted, and a page list page indicating a list of Web pages in the extracted range is displayed as the user terminal 1. The system control unit 24 may be configured to determine the range of the Web page information to be extracted based on the screen size acquired from the user terminal 1. For example, the larger the screen size, the larger the range of extracted Web page information is determined. As an example, when the acquired screen size is equal to the screen reference size, a Web page with a display order ranging from 1st to 10th is determined, while when the acquired screen size is smaller than the screen reference size, display is performed. Web pages in the range of the first to fifth ranks are determined. If comprised in this way, the list of the said web page can be displayed in the range suitable for the size of the screen in the user terminal 1, and the legibility by the user of the user terminal 1 can be improved.

[5. Adjustment of interest level by display character size]
In the above embodiment, the information providing server 2 adjusts the degree of interest by weighting according to the display character size in the Web page displayed on the user terminal 1 when calculating the degree of interest based on the scroll operation information. You may comprise as follows.

  In this case, the Web browser of the user terminal 1 creates an operation information file including the display character size information indicating the display character size in addition to the scroll operation information, the site ID, and the page ID. The ID is transmitted to the information providing server 2.

  And the system control part 24 of the information provision server 2 will acquire scroll operation information, site ID, page ID, and display character size information from this operation information file, if the operation information file from the user terminal 1 is received, In association with the user ID, scroll operation information, site ID, page ID, and display character size information are registered in the operation information database 224.

  Then, the system control unit 24 of the information providing server 2 extracts the scroll operation information, the page ID, and the display character size information associated with the user ID from the operation information database 224, and based on the extracted scroll operation information. Thus, when calculating the degree of interest, the degree of interest is adjusted by weighting according to the display character size indicated in the extracted display character size information.

  For example, when the interest level is calculated using the formula Sc (interest level) = α (arbitrary coefficient) / v (scroll operation speed), α is weighted, and the displayed character size is a predefined character reference size. If it is smaller than (for example, medium), the interest level is adjusted by making it smaller (for example, α = 80) than “α” (for example, α = 100) when the displayed character size and the character reference size are the same. . This is because if the displayed character size is smaller than the character reference size, it takes time to grasp the contents of the Web page and the scroll operation speed tends to be slow (that is, although the user is not very interested in it). This is because the degree of interest increases).

  On the other hand, when the display character size is larger than a predetermined character reference size, it is larger than “α” (for example, α = 100) when the display character size is the same as the character reference size (for example, α = 120). ) To adjust the degree of interest. This is because if the displayed character size is larger than the character reference size, it takes a short time to grasp the contents of the Web page, and the scrolling operation speed tends to increase (that is, although the user is interested). This is to increase the degree of interest.

  According to such a configuration, for example, even when one user uses a user terminal having a large display character size (for example, a PC) and a user terminal having a small display character size (for example, a PDA), Each degree of interest calculated using the scroll operation speed detected by each user terminal can be used in common. In addition, when one user uses one user terminal, even if the display character size is changed as appropriate, the scroll operation speed detected when the display character size is displayed is used. Each degree of interest calculated in this way can be used in common.

  Note that the degree of interest may be adjusted by parameters other than the screen size and display character size described above. For example, the degree of interest may be adjusted using a moving image and a still image. This is because, in the case of a moving image, unlike a still image, the user needs to consider the time because the user pauses or slowly scrolls the scroll operation in the moving image portion. In this case, for example, when a moving image is being scrolled, the degree of interest is adjusted by making it smaller (for example, α = 50) than “α” (for example, α = 100) in the case of a still image (for example, α = 50) ( That means lower interest).

  It should be noted that Web page information from a Web page list configured in the display order of each Web page to a predetermined range is extracted, and a page list page indicating a list of Web pages in the extracted range is displayed as the user terminal 1. The system control unit 24 may be configured to determine the range of the Web page information to be extracted based on the display character size acquired from the user terminal 1. For example, the larger the display character size, the smaller the range of extracted Web page information is determined. As an example, when the acquired display character size is equal to the character reference size, a Web page with a display order ranging from 1st to 10th is determined, while the acquired display character size is smaller than the character reference size The Web pages whose display order is in the range of 1st to 15th are determined. If comprised in this way, the list of the said web page can be displayed in the range according to the size of the display character in the user terminal 1, and the easiness for the user of the user terminal 1 to improve can be improved.
